We break down all the options possible for the Separ Filter SWK-2000 Series. The fuel water separators have versions suitable for marine, agricultural, construction, and power generation applications.

Single Filter Vs. Duplex Filter
For marine applications, we highly advise installing duplex filters, especially when a vessel is fitted with only one propulsion engine. Duplex filters have a primary and back-up filter. When the primary filter requires maintenance, the user can manually switch to the back-up filter without having to stop the engine. The user can then service the filter at a more convenient time and eliminate downtime.

Clear Bowl Vs. Metal Bowl
The advantage of a clear bowl is that you can monitor the water level and the degree of collected contamination without sensors. For marine applications, the clear bowl must also be equipped with a metal heat deflector for safety and protection purposes. The clear bowl is only offered in the 3 smallest model sizes:
SWK-2000/5
SWK-200/5/50
SWK-2000/10
Metal bowls are designed for harsher environments and is resistant to a broader range of temperatures. All model sizes can be available with metal bowls. Metal bowls should be purchased with water contacts.

Water Contacts
Connect a remote audio or visual alarm of your choice to the bowl's water contacts. When the water level in the bowl has reached these sensors, the alarm can alert the user when the bowl must be drained. It is highly recommended to purchase metal bowls with water contacts.

Vacuum Gauge
The gauge indicates the differential vacuum in the filter and is installed on the filter lid. It is a key indicator to determine when the element is clogged. Use this as a tool to help determine when backflushing or element replacement will be required.

The Separ Filter compound vacuum gauge is a useful indication of upcoming maintenance and filter element replacement. The red needle shows the maximum vacuum that has occurred (and is resettable to zero). The black, active needle shows the current vacuum reading. Maximum allowed vacuum is specific to engine manufacturer and can vary within 10-13 inHg.

When part of an engine fuel system, a reading of 8-10 inHg is a sign that backflushing is required. We suggest keeping a record, because the filter can be backflushed up to 5 times before element replacement is necessary. This procedure extends filter element life and the gauge is a clear signal for timely maintenance. As a result, elements are used efficiently and you keep costs to a minimum. Replace the element at least 1 time per year. (Download backflushing instructions or download element replacement instructions.)

Gauges can not be installed on lids that have not been tapped for it. If your existing filter(s) does not have a gauge, you can easily purchase a new lid and gauge assembly. Save 10% now at our online store on the assembly.
